Daniela Villalba's crime in Cordoba: what the autopsy revealed, the doubts about the motive and the last messages
The murder investigation into 29-year-old Daniela Villalba, whose body was discovered in her apartment in Cordoba, Argentina, remains open with authorities refusing to close off the hypothesis of femicide despite considering alternative motives such as robbery, contract killing, or mafia-related disputes. Preliminary autopsy results indicate the victim was decapitated and sustained defensive cuts on her arms, while forensic teams collected samples under her fingernails to identify potential DNA traces from the assailant. The case began when garbage collectors found a blood-stained suitcase containing personal items and an airport ticket bearing Villalba's name, leading police to her residence after a friend reported her disappearance and noticed a strong odor in the hallway. Investigators are currently analyzing security footage of low resolution that captured a man entering the building, along with a sequence of WhatsApp messages sent late Monday night where Villalba allegedly mentioned having a client before going silent. The article notes that Villalba reportedly worked as a sex worker, a detail highlighted by investigators as they scrutinize the timeline and communications from
The body of a 32-year-old woman was discovered in a drainage ditch in the southern Argentine city of La Plata after she attended a community gathering, leading police to detain a 33-year-old man who had been seen with her hours before her death. Lucy Rueda Batallanos was found dead on Monday morning in a ditch located along Avenida 66, between streets 197 and 198, in the locality of Lisandro Olmos. Preliminary autopsy results determined that she died from severe traumatic brain injury accompanied by a subarachnoid hemorrhage. Authorities have opened an investigation into the case as a femicide, placing it under the jurisdiction of the Eighth Functional Investigating Unit of La Plata, led by Prosecutor Martin Almiron. Investigators reconstructed the victim’s movements based on testimony from attendees at an event known as the "Alta Fiesta," held near the intersection of streets 208 and 52. Rueda Batallanos arrived at the celebration with a female friend and remained there for several hours. Around 3:00 a.m. on Monday, the friend left the venue with another woman. According to witnesses, Rueda Batallanos stayed behind and engaged in conversation with a man wearing a red garment. This detail became a primary lead for detectives from the Tactical Operational Group of the Fifteenth Police Station. Concern grew among the victim's circle as she failed to check in during the early morning hours. At approximately 6:57 a.m., a friend received a photograph via a WhatsApp group showing a woman lying beside a road ditch. Although the image was initially unrecognized, Rueda Batallanos' sister later confirmed that the person depicted was her sister. This confirmation prompted an immediate search effort that resulted in the discovery of the body. Police focused their efforts on identifying the man described by partygoers. Descriptions pointed to an individual known by the nickname "Dani." Investigators traced this alias to Ausberto Marquez Aguilar, a 33-year-old Bolivian national. Officers located him at a residence situated approximately 300 meters from the site where the body was found. Upon being apprehended, Marquez reportedly made informal statements indicating he had attended a party, consumed alcohol, and returned home, adding that he did not remember specific details because he was heavily intoxicated. Judicial sources clarified that these spontaneous remarks do not constitute a formal investigative statement before the prosecutor. Following his arrest, the court authorized a search warrant for Marquez's home. During the raid, officers seized clothing items stained with blood. These garments were submitted for laboratory analysis to determine if they are linked to the homicide. Additionally, investigators ordered a review of public and private security cameras installed along Avenida 66. The objective is to reconstruct the movements of both the victim and the suspect after they departed the party location. The forensic examination detailed the specific nature of the fatal injuries. The medical report describes the traumatic brain injury as a high-intensity lesion caused by a blunt impact to the skull, which directly affected brain tissue. The accompanying subarachnoid hemorrhage involved the rupture of blood vessels, causing massive bleeding in the space between the surface of the brain and the surrounding arachnoid membranes. This combination led to a rapid increase in intracranial pressure, interrupting blood flow and oxygen supply to vital areas of the central nervous system. The incident has drawn attention to the broader context of gender-based violence in the region. While the current focus remains on the specific circumstances of Rueda Batallanos' death, the case contributes to ongoing statistical tracking of femicides in Argentina. Prosecutors are working to establish the exact sequence of events following the party, relying on witness accounts and digital evidence. The detention of Marquez marks a critical step in the inquiry, though the legal process continues as forensic results pending. Witnesses at the "Alta Fiesta" provided consistent descriptions regarding the victim's last known companion. The man was noted for his attire, specifically the red top, which aided in narrowing down the suspect pool. The transition from the social gathering to the scene of the crime remains a focal point for the tactical police unit. They are analyzing gaps in communication and physical movement to build a coherent timeline. The proximity of the suspect's residence to the discovery site offered logistical advantages for the initial response team. The seizure of blood-stained clothing introduces a tangible element to the investigation. Laboratory tests will seek to match biological traces with the victim or other potential parties involved. Meanwhile, the review of surveillance footage aims to capture any visual record of the two individuals traveling together or separately after leaving the event area. The integration of these digital records with physical evidence is standard procedure in such cases. Prosecutor Martin Almiron oversees the proceedings through the designated functional unit. The classification of the case as a femicide reflects the preliminary assessment of the motive and the relationship dynamics, although final legal determinations await the completion of all evidentiary processes. The family of the victim has been kept informed of procedural developments. Local media coverage has highlighted the swift action taken by law enforcement to locate the suspect within hours of the body's discovery. The case underscores the challenges faced by investigators in urban environments where multiple witnesses and fragmented timelines exist. The reliance on informal statements from the suspect adds complexity, as these comments lack the legal weight of sworn testimony. However, they provide context regarding the suspect's claimed state of mind and memory at the time of the alleged offense. As the investigation progresses, authorities continue to gather corroborating data to substantiate the charges against Marquez Aguilar. The outcome of the forensic analyses on the seized clothing will likely play a decisive role in the next stages of the judicial proceeding.
